Mayor Tony Kennon and the council directed city staff to thoroughly research the health implications of e-cigarettes to the public. In late April, the Food and Drug Administration announced plans to begin regulating e-cigarettes as tobacco products for the first time. The proposal would ban sales to minors, require companies to use warning labels and register with the FDA, reporting product and ingredient listings.

"We've all been overwhelmed and the research is three-feet thick," Councilman Al Bradley said after Tuesday's meeting, where the council tabled the measure. "I need to read it to make sure that this is the right thing. My gut says it is."

Councilman Jerry Johnson, who approached the council last month about the need to begin protecting the public's exposure to e-cigarettes, said it will likely come to a vote in June.

"We're making sure we read all the research and make sure we're making the best decision," Johnson said.
